To all whom it may concern:

Be it known that l, EMANUEL E. None oUis'r, a citizen of the United States, residing at ltansas City, in the county of Jackson and State of Missouri, have invented certain new and useful improvements inv Sheetlletal ilulverts, ot' which the following is a speci ication.

This invention relates to culverts and more especially to sheet metal culverts, and nay object is to produce a device of this charac ter ol auch torni to reliably anchor itself against endwise creepage or movement and torni guards tending to hold intact the superposed side portions ci' the overlying road and thereby incidentally protect itself against injury by the wheels of vehicles traveling on such road,

l further object is to produce a culvert, having' a flaring nioutli to act as a c oncen trating noz/isle lor accelerating the flow of water through the culvert at times' and-incrdentally protect `the earth in the immediate vicinity of the receiving end oi the culvert from washing away and also tend to prevent rodents from bur-rowing through the roadway along or very near the top of the culvert and thus weakening theroad. Y

A further object is to produce aculvert hav ing strong and rigid Haring mouth against which bunches ol weeds or other matter carried by the water may be more readily broken up by the force of the latter than `would be the case il such debris lodged against the end ol the relatively small bodyportion of the culvert.

Astill further object is to produce a culvert which can be installed at a Ininimuin cost and may be of lnioclr-down construction to facilitate handling and shipment. I

Vith these general objects in view, the invention consists in certain novel and peculiar features ol construction and organization as hereinafter described and claimed; and in order that it may be fully understood refery ence is to be had to the accompanying drawing, in vvhich;- 4, l

ldigure l, is a vertical transverse section of a road equipped with a culvert embodying my invention, theculvert beingshown partly in elevation and partly in longitudinal section. llig. 2,is a cross section of the culvert on the line lll-ll oi Fig. l. Fig. 3, is an enlarged fragmentary section of the culvert.

ends in smooth or non-corrugated cylindrical ends 3; one of the ncn-corrugated ends of one of the sections being fitted snugly in an li Il Vplurality of sections 2 terminating at their v dll end of the adjacent section and secured rigidly thereto by rivets 4, orotherwise.

The length of the body ol the culvert will preferably be less than the width of the road, irrespective of the nuinber of sections of which such body is composed, and at each end it will be provided with'a flaring Iiioi or funnel 5, the reduced ends of the funrbeing snugly embraced bythe juxtaposed ends of the bod and rigidly connected to the same by angle brackets riveted as et 7 or otherwise to the tunnels and bolted. as at?) or otherwise to the body, the outer'edges of the lunnels being reinforced andsti'lfened by angle-iron rings 9. The aggregate length ol' the body and funnel-ends of the culvert are substantially equal to the width of the road, as shown in Fig. l, so that the funnels form abutinents or lateral supports for the sides of the superposcd portions of the road and thus avoid the necessity ci unduly narrowing the saineby sloping it materially downward at its sides or necessitating the employment of a culvert as frequently occurs, consider ably longer than the width of the road. lt will also be noted that the tunnels tend to uard aeainst the side ortions .of the road g e Washing away immediately over the culvert in heavy rains and thus eventually exposing the latter to contact with the wheels of pass ing vehicles, which contact Vin time, will cut through and thus materially 'impair the strength and serviccability of the culvert.

A culvert of this character hasA a greater capacity than one of the same diameter throughout, as the tunnel at the receiving end acts as a nozzle 'to accelerate the flow of the Water through the body by creating` a suction therein. The funnel is advantaf eousalso in that an obstruction such as a ence vrail, bridging the saine will be sub jected to greater leverage from a rush of wa` ter and` debris than iflodged across the mouth of the body and hence will break more.

readily-under such pressure and .thus eliminatejin a material agree the possibility of the culvert becoming choked and failing to lllll vitto ,body end theinlmelelieped `end-portions', it
